MIXER son LIQUIDS on SEMILIQUIDS.

Specification of Letters Patent.

Patented Jul -re, 1907.

Application filed October 3, 1906' Serial No. 337,217.

To all whom it may concern: Be it -known that I, ELBR-IDGE G. HOLDEN, acitizen of the United States, residing at Home City, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in a Machine or Device for Mixing, Purifying, Aerating,&c., Liquids or Semiliquids, Preferably Named a Mixer.

My invention relates to that class of mixer by which the materialtreated thereby is thoroughly agitated and is subjected, simultaneouslywith said agitation, to forceful currents of air which pass through it.

The objects of my invention are: first, to provide a mixer simple inconstruction, durable and cheap; second, to provide a mixer which adaptsitself inany shaped receptacle of reasonable size and having anadjustable shaft adapted to operate at any position from. a vertical toan angle of forty-five degrees or more; third, to provide a mixer soconstructed as to revolve an inner receptacle, in which it works, byimpingement of the material treated against the inner side of saidreceptacle made revoluble by floating in water or other liquid. I attainthese objects by means of the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a verticalview of the mechanism with asectional view of the receptacle. Fig. 2, a top view of the actuatingmechanism.

Similar numerals refer to similar parts throughout the drawings.

In Fig. 1, 1 is the receptacle in which or to'which the mechanism isattached, as hereinafter more fully described, 2 the driving wheelmeshed into teeth on pinion 3, 4 being top section of a sectional shaftdesignated as parts 4, 5 and 6, 4 being a hollow section into which thereduced section 5 is adjustably retained by thumb screw 9, the lower endof said section 5 is permanently connected to section 6 which is thelargest section of said sectional shaft to which the blades 7 arefastened in said section 6 in grooves or otherwise at an angle aboutforty-five degrees by means of screws or other suitable means, 10, 10,being a support for pinion 3, upper section 4 is retained in place by apin or other suitable means, 12, 12, being parts of clamp 11, of which13 is the thumb-nut on bolt through the top portion of the clamp, ashereinafter more fully described, as will also be the means ofengagement of the mechanism to said clamp which clamp is retained bycontacting the inner lug 12 of the clamp to the inner side of thereceptacle by means of thumb screw 14, 15 indicates the handle attachedto the driving wheel 2 for the purpose of operating the mechanism, 19showsan inner receptacle designed to float in fluids, in which thematerial to be treated may be placed. Said inner receptacle is that towhich I l we havehereinbefore alluded as revolving by the force of thematerial impinging against the side while the mechanism is in operation.

In Fig. 2, 16 being one member of the toothed clamp to which we havehereinbefore alluded, 17 being the upper portion of clamp, 18 being thatportion of the toothed clamp which is a part of the U-shaped part inFig. ],"of which in said Fig, 10, 10,' are supports etc;,' as previouslydescribed, said toothed clamp 16 has said parts 17 and 18 reciprocallytoothed for setting the dash or shaft at any desired angle up toforty-five degrees or more and by tightening the thumb nut 13 the shaftwill be retained rigidly in position as indicated by dotted lines inFig. 1.

My mixer is assembled and operatedas follows: Into receptacle 1, liquidor other fluid maybe put-into.

which the inner receptacle 19 may be put about which hot water or waterand ice may be put to produce a desired temperature for the materialbeing treated. The clamp 11 is rigidly fastened to the outer receptacleby means of thumb screw l4, the upper section 4 extending up throughsupports 10, 10, the pinion 3 is retained rigidly to the upper section 4of shaft by means of a pin, 10A having a pin as the means of retainingthe drive wheel 2 on its bearings. These assembled parts are thenfastened to the clamp already on the receptacle by means of the toothedclamp whose respective parts 17 and 18 are clutched together, retainingthe combination or sectional shaftin any desired position from avertical to any angular position by means of thumb nut 13 as shown inFig. 1, sections of the shaft 5 and 6 are permanently engaged, and the,length of the shaft is regulated by raising section 5 up into the hollowsection 4 and retaining it therein by means of the thumb screw 9. Y i Itis obvious that my mechanism is adapted for use in any sized vessel orreceptacle from one large enough to permit the revolving of the wings upto a vessel two feet or more in diameter. The receptacle may becircular, oblong or angular.

Receptacle 19 may be used when desired to maintain a requiredtemperature by means of putting into the outer receptacle a suificientquantity of fluid to give buoyancy to the inner vessel, so that theimpingement of the fiuid or material being treated in said inner ves-'sel will revolve, as may be advantageous in the making of ice-cream, ormaintaining the better temperature for butter making in summer time bythe application of ice and water or hot water in the outer receptacle,or hot or warm water applied in cold weather, etc.

It is apparent that my mixer as such may be used with the outerreceptacle alone for the treatment of different fluids.

The adjustable features of my shaft gives valuable points of advantageover a vertical shaft, especially as iollows:-it will operate in varioussizes or shapes of vessels; it creates greater agitation, and indu'cts'much more air. p

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is,-

1. In a mixer of the class described, a shaft sectionally made, a hollowsection 4 thereof adapted to receive portions of section 5, said section4 provided with thumb screw 9 as the means of-retaining sections 5 and 6to said section 4, blades set angularly on said section-6, and the meansfor retaining said blades to said'shaft' section, the pinion 3 'onsection 4 and the means for securing said pinion to said shaft section,substantially as described and :for the purpose set forth.

. screw 9 as the means of retaining sections 5 and 6 to said said'toothclamp section 18, said engagement maintained by thumb nut 13, and bolttherefor, said lugs or portions 12, 12, clamped .to receptacle '1, bymeans ofthumb screw' 14 and the actuating driving wheel 2 and handle 15as the means of operating the entire mechanism, substantiaily asdescribed and for the purpose set forth.

I have hereunto set my hand in the presence of two subscribingwitnesses.
